Is there a way to tweak the behaviour of the auto-brightness backlight? At the moment it correctly goes up to full brightness in sunlight, but it doesn't go as dim as I would like under artificial light. At home, after dark, under electric light, I can manually turn the screen brightness down to the minimum level, and it's still bright enough - the auto setting is much brighter than that(although clearly much dimmer than it is in sunlight, so it is doing something).
Can this be tweaked? Failing that, is there an easier way to control the brightness manually - something I can keep running all the time, and which doesn't require the stylus to change the setting?

Thanks, I'll give that a try.
I find Lumos to be more stable and reliable

Ok I havn't tried either of them before but I just installed G-Light.
After a bit of config. it's ok. You need to give each backlight number a wider setting.
Otherwise it'll just flip back and forward in brightness.
So far G-Light is proving rather dissapointing. The phone's built-in "Auto" setting works well, apart from the fact that the brightness doesn't go low enough in dim light - in particular, it manages to choose a good level and then stick to it. G-Light, by contrast, keeps changing the brightness up and down all the time.
I think the notion of having absolute brightness bands may be the wrong way to go. You really want a set-up where the threshold values are in different places depending on whether the light is getting brighter or dimmer. So, as the light fades, you cross a threshold and dim the screen - but when the light goes slightly back up over that threshold, you don't brighten the screen again until it gets significantly higher than that. That way, regardless of the light level, the screen brightness will be steady unless the ambient light level is changing a lot. If you use single threshold values then whenever the ambient light happens to be very close to a threshold value you will always get the brightness going constantly up and down.
Edit: some of the things Lumos does (like averaging across multiple readings) sound hopeful, though. I'll give that a try.

Let me know how Lumos is.
Yes as I said earlier you need to widen those settings.
For now I have 5 set to 0-81
6 set to 82-200
8 set to 201-600
10 set to 601-1000
All the rest are disabled by setting the values to -1 to -1

Lumos is also proving dissapointing. It's partly the fault of the hardware - the sensor seems to read 0 even in surprisingly bright light, so the app has no way of telling whether you're at a light level where backlight 1 is appropriate or a light level where backlight 3 is appropriate - both read 0 on the sensor. (This is probably why the default auto option doesn't go below 3 in the first place).
As for Lumos, the author needs to realise that perception of brightness is actually based on an exponential curve. That means that all of the values between level 1 and level 5 are somewhere between 0 and 80 sensor reading. The graph interface is useless for editing custom values with that level of precision - it's trying to squeeze over 2000 values into less than 800 pixels of screen space, and the pixels are tiny! I think you can edit the values directly in the settings.txt file, but that's fiddly - there should be spinboxes, really (as with G-Light).
In any case, you don't want to be editing the values directly! What you want to be doing is taking the phone out of your pocket, looking at it, and thinking "hmm, the screen is too bright at the moment" then adjusting the brightness to whatever level is comfortable for the current ambient light level. The programme should then interpolate the curve that you want, and progressively refine it each time you decide it isn't quite right and tweak the brightness.
I haven't tried to Lumos program yet, but I've been using Glight for a few days. At first I had some issues with it but then I realized that you have to turn the auto light adjustment off in settings first. If not, they'll both be fighting against one another.
Also, you have to set your thresholds pretty carefully as has been already stated. Mine is set to go bright only in bright outside and lowest in a dark room with no light at all.
1 0 to 5
3 10 to 799
8 800 to 2500
I've got mine set low for better battery life and the screen is always readable to me no matter what anyway.
Also, if you're using a the snap on rubber protector (I got a T-Mobile one) it will interfere with the light sensor. I just got one and the lighting is all over the place now. Time to order a full body screen protector.
GLight doesn't seem to work for me. keeps crashing, and the settings don't seem to save at all.
I don't want a sliding scale that Lumos has since i don't think the light sensor is all that accurate (sometimes thinks it's too bright and sometimes thinks its too dark). would rather just have a few settings (pitch black setting, super bright setting, and in the middle) as shawndh suggested.
i have the verizon tp2 - not sure if this might be causing some of the glight probs.
Sometimes when I'm in a dimmer area, my display will be so dim I can hardly see it. This doesn't happen in brighter areas.
For reference, it is far far dimmer than brightness setting 1. I have the watch set to auto brightness and ambient off.
Anyone else seeing this?
Yeah, it seems that the 360's auto brightness setting is (at least sometimes) pretty aggressive in low light conditions.
Same here, and I hate that. I always have to go into the settings when the room light is dim, and switch off auto brightness and change to the 1 setting.

I'm almost positive it's a bug, the low brightness of 1 isn't too bright for very dark situations and the dimmed mode is simply too dim.
I'm pretty sure auto-brightness should turn on at level 1 (if it's dark) and then go to the ultra-dimmed mode before the screen times-out just like in normal brightness.
I don't think I've seen this bug happen in the daytime though, so it does seem like a bug at brightness level 1 only
Any solution to this problem? Drives me crazy.
Thanks
Smart Brightness for Moto 360
Try Smart Brightness for Moto 360. This application allows to set auto brightness with a minimum brightness to avoid a dimm screen on dark situations.
https://play.google.com/store/apps/details?id=com.makinke.smartbrightness
I set my watch to use auto brightness. In a dark location, like movie theater or dark room, the auto brightness is not working properly:
- when I receive notification, the watch screen turned on at the full brightness. After about 2 seconds, then it either turn off the screen or the brightness reduced.
- when I wake up the watch manually, same thing happen.
Anyone experiencing this?
I usually see the opposite, where in a dark room, it comes on so dim that I can 't even see it, then brightens after a couple seconds. However, your general point is right on... the auto-brightness definitely needs some improvement.
Hmmm...That's interesting.
Really tick me off when I just woke up and the bright screen blast my eye. I am using the watch with sleep android app, but I think I'll forgo that.
Auto brightness in dark situation for me is terrible. It is even dime than level 1 brightness. I can only see time, but can not read notification clearly. I change to level 1 setting, it is great. And save lots of battery as well.
Moto 360 Brightness
Try the application "smart brightness for moto 360" from the Google play. With this application you can set a minimum brightness and better view in low light environments.
With the minimum set to 20% and auto brightness on you will get better battery life and better experience in dark situation.
Under display settings, there's this "Auto Adjust Screen Tone" that confuses me. Looking for the explanation as for what it does, I found it supposedly plays with the screen brightness based on the on-screen image, but it's very vague. What's the point of having both this and auto brightness? How do they work together?
Setting it on and off shows absolutely no difference. Does it really save battery at all?
Doesnt really do much for me either. I think its for a better accurate brightness level when you turn on auto brightness. When you turn on auto brightness and the adjust screen tone I think that would mean that the auto brightness would adjust its brightness by the sensor next to the front camera and the auto adjust screen tone would adjust to the image being displayed makeing the brightness best for the envrioment your in(how much light is in your room). Lets say your in a dark room and your trying to veiw a dark image, so the screen would get brighter even if the sensor is saying "theres no light here" based on the screens image. Thats my guess and someone correct me if im wrong. Idk if it saves battery but I just adjust my screen brightness manually.
It should actually be an attempt to match the color temperature of the screen to your environment. For example if you're outside it'll shift everything more blue (around 5,500 degrees kelvin) than if you're indoors with a "warm white" lamp lighting the room (closer to 3,200 kelvin). All this in an attempt to make colors appear more accurate wherever you are. It's safe to assume it uses the camera to read the colors of your environment, I'm pretty sure the light level sensor only measures luminance (brightness). Hope this helps.

^^^ that's what you'd think from the name, but if you read the description it says adjust display brightness based on image on screen to save battery. So I think for example if you have a mostly white screen it'll reduce the brightness. If done right, you won't notice it because it'll still look plenty bright.
Has nothing to do with temperature. I wish there were a feature for that.
I'd try it for a while to see how it feels. Probably a good feature.
This is my first AMOLED screen phone and something I think I may be noticing that maybe you guys can help confirm or deny about AMOLEDs vs LCDs, is that at night when turning the brightness down (way down, like -50 in the Lux Dash app as an example) results in getting the screen to a point where not bright enough to hurt your eyes at all but the blacks are too dark. So there's no real ideal brightness setting in a dark room that equals no eye pain but still allows you to able to see everything on the screen. Or are my eyes just too sensitive and most other people don't need to turn it down as much as I do and therefore don't have this problem?
You tried night mode
Lux is garbage. Factory adaptive brightness and still being able to use the brightness slider to allow on-the-fly adjustments is far superior - it works perfectly on this phone. And in a pitch black room, with adaptive brightness, setting the slider from 0-25% results in an extremely dim screen (1-2 nits) will information still perfectly viewable. Blacks may have uniformity issues, but that is the nature of OLED panels since it is extremely hard to control voltage at near-black levels when the brightness is extremely low.

Amoled displays, when used with automatic brightness adjustment, have a small problem - when you are viewing them in the dark, they appear too dark. Their contrast ratio is infinity, which means that dark colors are basically zero luminosity or close to zero. A lot of internet imagery is calibrated for lcd displays, so when you lower your phone brightness to make the brightest parts viewable on an amoled display, the dark colors become too dark and blend together. This is especially true when you are viewing a screen in a dark environment. There's nothing you can do but increase device brightness by hand when you are using automatic brightness adjustment and viewing in the dark,

You do realize that Adaptive Brightness simply changes the brightness of the screen in response to the light sensor reading?
In other words, the phone doesn't care about your preference - it will change the brightness to preset levels.
On Samsung phones, this situation is far more intelligent. The phone still uses the light sensor to adjust the brightness, but the phone also applies a user preset to augment the brightness - when you slide the brightness slider up, the phone will make auto brightness adjustment higher, and vise versa.

WHAT? You have it totally backwards. Stock Android, including the Pixel, uses user input to augment the auto light sensor brightness when adaptive brightness is enabled. If my phone thinks 50% brightness is appropriate, but my slider is set to 100, it will choose something like 75% brightness instead. If I drop the slider to 0% in the same instance, it might choose 25% instead. The user preference will ALWAYS be impacting auto brightness.
Samsung phones, unless it changed with Nougat, rely strictly on what the phone thinks is best for auto brightness. The user can adjust the slider with auto brightness on, but the slider is a direct adjustment 0-100% of the true brightness level, and the slider will change automatically when there is a large shift in ambient light after the display has been turned off at least once. User preference does NOT impact auto brightness unless you set it at that specific moment.

I have a Note7, Pixel XL, and LG V20. Google how adaptive brightness works. There won't be a single article that matches how you say it works.

If you seriously can't tell how adaptive brightness works just by using it as compared to Samsung and LG, I don't know what to tell you. It's pretty damn obvious. If I'm the kind of person who prefers a bright screen, I can set adaptive brightness to 100% and it will always be bright, but stay relative to the ambient lighting. If it's a dim room, the screen will be bright, but nowhere near 100% manual brightness. It only hits 100% manual brightness when under bright light like the sun.
Samsung's auto brightness is still very cookie cutter. If you put 2 Samsung phones side by side with auto brightness on, they will always be the same no matter the ambient light. If I take 2 Pixels, both set to adaptive, and put one on 25% and one in 75%, they will always maintain a brightness difference even when ambient light changes. Samsung phones do not maintain user preferences once the ambient light level changes. I almost never have to adjust my Pixel. I always have to adjust my Note7 because I prefer a slightly brighter screen.

What you are saying is EXACTLY THE OPPOSITE of my experience with Note 7 and Pixel XL. I NEVER had to adjust my Note 7 brightness once I set it.
I find myself constantly adjusting Pixel XL brightness setting.
Maybe they both have "adaptive brightness", but the Note 7 version was perfect, and the Pixel XL is just sh`1rt.

Or maybe you two just have differing opinions on what a "perfect" brightness setting is...
Doesn't matter how you adjust your brightness. I'm just saying that when brightness is low, blacks are darker and disproportionate to other colors.
I love Lux especially with it's profiles. Much better control and accuracy than adaptive brightness. I just wish Lux had an auto-profile switcher based on time of day. I have a day profile, night profile, and car profile.
One thing to note is that Lux allows me to bring the darkness down below 0% to negative values, which is where I usually notice my concerns. But that's what I need to not hurt my eyes at night. So I don't blame the phone or anything - just posted this article out of curiosity. The blacks are probably just turning off completely at some point when I bring the value to below 0% which I think makes sense based on the nature of OLED.
You should just turn on night mode to help with eye strain. If 0% brightness is too bright I don't think you will ever get lux to work the way you want, but night mode helps my eyes a lot.
Pixel XL adaptive brightness adapts to what you set the brightness to. If you go from 0 to 100 in a totally dark room, you notice how the screen stays really bright and doesn't go back to 0 on Pix
Many phones use auto brightness to fullly determine brightness based on sensor and ignores user brightness. If you go from 0 to 100 with an auto brightness phone, the phone will go back to 0.
Some prefer one over the other.
